Anyone know what these are

I know the pictures are not the greatest but I deleted more than I kept! We have one Nassarius snail, one conch a shrimp and a diamond goby. All these are looking at the bottom of what look like snails through the glass. I could not get a picture of the top of what it looks like some type of snail.

Stomatellas or limpets probably, either way beneficial. @ISpeakForTheSeas?

In this case limpets or chitons (limpets have a solid shell, chitons have segmented shells) - but yeah, most likely harmless/beneficial.
